Yes, I was hoping they would run the Mondie, however, I think they'd be too big and unwieldy to be competetive.
Also, all the engine development, which was a bit I imagine seeing as they have to sleeve a 2.5lt 5 cylinder engine down to 2lt, has already been done by Volvo for the C30, so it's a logical step to use the Focus, assuming they are going to use the same engine, and not some other 4 cylinder lump.
